Question

Are there any parts of the human body that get oxygen directly from the air and not from the blood?

Answer 1

As far as I know, I don't think any of them get it from the air directly.
Considering that the blood goes throughout the body and supplies energy to every body part.

Answer 2

Yes

Answer 3

Well parts of the human body don't get oxyen directly, oxygenated blood provides oxygen needed for the organs to work properly from what I understand (correct me if i'm wrong)

Answer 4

So no it cannot because blood filters and is only oxygen and gets rid of the CO2 so the only way ur body can get oxygen is by filtering it so u cant get oxygen directly until it is filtered and is only oxygen no carbon dioxide
